Question

for each expression combine like terms and write an equivalent expression with fewer terms a. 5 + 2x + 7 + 4x b. 4 - 2x+5xc. 10x - 5 + 3 x - 2

Answer 1

a) 5 + 2x + 7 + 4x

By combining like terms, we would add the terms containing the variable, x together. We would als add the constant terms(not containing the variable, x) together. It becomes

2x + 4x + 5 + 7

= 6x + 12
