Now, before we start, I just want to make this clear - no guessng, or using any online sites. Also, you can use a calculator. So, are you going to try?
2w + 2 = 16
w=7
w=9
w=8
w=5.5
10c + 4 = 4c + 64
c=10
c=9
c=22
c=-2
10x - 7 = -107
x=10
x=-10
x=-5
x=5
2x + 7 = 8x + 55
x=-8
x=8
x=16
x=-16
7z + 10 = 8z + 14
z=-4
z=4
z=-3
z=3
5a + 4 = 9a - 40
a=11
a=-11
a=10
a=-10
5y + 3 = 11y - 39
y=7
y=-7
y=8
y=-8
4(7x + 2) + 9 = 9x - 173
x=-11
x=13
x=-14
x=100
