The equation that does NOT give the correct value of g is:
7(g – 3) = 42
Mika’s gym allows her to bring 3 guests for free. After the first three, she must pay $7 per guest. How many guests, g, can she bring to the gym if she pays $42?
Three of these equations give the correct value of g. Which equation does NOT?
CLEAR CHECK
7g = 63
7(g – 3) = 42
7g – 3 = 42
g = 9
