Leeza did this work to solve an equation. Did she make an error? 4x 4x == 7 3(2x−5) 7 6x−5 CLEAR CHECK Leeza made an error because she should have simplified inside parentheses first. 4x=7 3(−3) Leeza made an error because, when removing the parentheses, she also needed to multiply −5 by 3 . 4x=7 6x−15 Leeza made an error because she should have subtracted 2x from both sides. 2x=7 3(−5) Leeza did not make an error.
