A) 9A = 3A ± 6 B) ±5 + A = 6A C) A ± 5 = 4A D) 2) If ±6X + 12 = 0 And 4Y.
Students should be encouraged to show their work in stepwise fashion. 4x + 7 = 15 −7−74x= 8 44 = 2 3 6 + 3x = 15 −6 −63x= 9 33 = 3 5 41 = 8x − 23 +23+23 64 = 8x 88 8 = xorx = 8 7 9x + 7 = 88 −7−79x= 81. Students will draw on their algebra.
A+9 12 = 2 A+9 = 24 A = 15 A = 15 2.
You’ve solved the equation when you get the variable by itself, with no numbers in. Mcq 1) identify the equation which does not have a solution at a = ±1. 5w +4 11w = j2j 6w +4 = j2j 6w +4 = 2 6w +4 = 2 6w.
