The question is 7+x=0-6x
1. First, isolate x, which is 7+x-7+6x=0-6x+6x-7
2. Second, simplify, which is 7x=-7
3. Divide both side by 7 to isolate x, which is 7x/7=-7/7
4. The answer is x=-1
x3-4=2 Add four to both sides. x3=6 Take the cu=6 be root of both sides. x is equal to the cube root of 6, or approximately 1.81712.

4 - 4x = -12 Subtract 4 from both sides: -4x = -16 Multiply both sides by -1: 4x = 16 Divide both sides by 4: x = 4
14 - 3y = 2 subtract 14 from both sides -3y = -12 divide both sides by -3 y = 4
2e - 12 = 7e + 8Add 12 to both sides: 2e = 7e + 20 subtract 7e from both sides: -5e = 20 divide both sides by -5: e = -4
x3-4=2 Add four to both sides. x3=6 Take the cu=6 be root of both sides. x is equal to the cube root of 6, or approximately 1.81712.

Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
4 - 4x = -12 Subtract 4 from both sides: -4x = -16 Multiply both sides by -1: 4x = 16 Divide both sides by 4: x = 4
x/3 - 7 = 2=> x/3 = 9 (add 7 to both sides) => x = 27 (multiply both sides by 3).
14 - 3y = 2 subtract 14 from both sides -3y = -12 divide both sides by -3 y = 4
2e - 12 = 7e + 8Add 12 to both sides: 2e = 7e + 20 subtract 7e from both sides: -5e = 20 divide both sides by -5: e = -4
To isolate the "x", you divide both sides (left and right of the equal sign) by 25.To isolate the "x", you divide both sides (left and right of the equal sign) by 25.To isolate the "x", you divide both sides (left and right of the equal sign) by 25.To isolate the "x", you divide both sides (left and right of the equal sign) by 25.
if you want to "solve" this equation, you need an equals sign somehwere! For example, if the problem was 2x - 52=5 then you could solve. You add 52 (or 25) to both sides so the equation becomes 2x = 30. Then you divide both sides by 2 to get x=15
-4x-6x = -20 -10x = -20 Divide both sides by -10 rembering that a minus divided into a minus the result is positive: x = 2
In simple cases such as these, you can solve inequalities just like an equation. In this case, you add 3 to both sides.
Add 2.9 to both sides. y = 8.2
