Thank You If you do help me.

Answer 1

1) -11



2) No solution



3) 1



4) 960



5)



a) x + 2 = 2( x + 3 ) + 4



x + 2 = 2x + 6 + 4

x = -8



b) 3( x + 2 ) = 2 ( x - 3 ) + 4



3x + 2 = 2x - 6 + 4

x = -4



Hope I helped :)

Answer 3

5x + 2 = 4x − 9

5x – 4x = – 9 – 2

x = – 11



−2(x + 3) = −2(x + 1) − 4

– 2x – 6 = – 2x – 2 – 4

– 2x – 6 = – 2x – 6

no solution



3(x + 1) = −2(x − 1) + 6

3x + 3 = – 2x + 2 + 6

5x = 5

x = 1



x = 0.6x + 384

x – 0.6x = 384

0.4x = 384

x = 384/0.4 = 960
