A/5 + 3 = 2Add Subtract 3 from both sides:A/5 = -1Multiply both sides by 5:A = -5

Subtract 3x from each side: 7 = 3x - 2Add 2 to each side: 9 = 3xDivide each side by 3: x = 3

5x + 4 = 6x - 2Add 2 to each side of the equation:5x + 6 = 6xSubtract 5x from each side:6 = x
4x + 2 < 8x - 2Add 2 to each side:4x + 4 < 8xSubtract 4x from each side:4 < 4xDivide each side by 4:1 < x

It's difficult. If you try too hard with this one, you'll zip right past it.-2x - 10 + 4 = 2Combine the -10 and the +4 on the left side :-2x - 6 = 2Add 6 to each side:-2x = 8Divide each side by -2 :x = -4
the square root of 2: 1.000 the square root of 5: 2.236 hope it helps
A/5 + 3 = 2Add Subtract 3 from both sides:A/5 = -1Multiply both sides by 5:A = -5

First of all, you have to know what you're looking for ... a number that you canput in place of 'x' and make the whole statement true. There's only one numberthat will work.-4 + 7 = 5x - 2Combine the numbers on the left side:3 = 5x - 2Add 2 to each side of the equation:5 = 5xDivide each side by 5:1 = x
3x - 2 = 2 - 2x.Add 2x to both sides: 5x - 2= 2Add 2 to both sides: 5x = 4divide both sides by 5: x = 4/5Check in original equation: 3(4/5) - 2 = 2 - 2(4/5) --> 12/5 - 2 = 2 - 8/5.12/5 - 10/5 = 10/5 - 8/5 --> 2/5 = 2/5
