Combining Like Terms Definition Examples Expii Welcome to an intro to combining like terms with mr. j! need help with simplifying expressions by combining like terms? you're in the right place!whether you. Steps to simplify expressions using distribution & combining like terms. step 1: distribute the term outside the parentheses to each term in the parentheses by multiplication. step 2: organize the. Matching signs = positive. negative × negative = positive. positive × positive = positive. ★combine like terms. positives and negatives are addition and subtraction. like terms match in both variable and exponent. so…. to combine like terms means merge matching terms, keeping the dominant ± sign…. ★an absolute value. Example 4. use the distributive property to combine like terms (if possible) in each of the following expressions: (a) −5 x2 − 9 x2, (b) −5 ab 7 ab, (c) 4 y3 − 7 y2, and (d) 3 xy2 − 7 xy2. solution. if the terms are “like terms,” you can use the distributive property to “factor out” the common variable part.

I confirmed this by substituting each value in the equation to see if the 2 sides are equal. in both cases, the 2 sides are unequal. here's correct solution: 1) combine like terms on right side: 3x 12 = 5x 2. 2) subtract 3x from both sides: 12 = 2x 2. 3) subtract 2 from both sides: 14 = 2x. 4) divide both sides by 2: 7 = x. checking solution:.
