7x-40 = -3x
Add 40 and add 3x to both sides:-
7x-40+40+3x = 3x-3x+40
10x = 40
Divide both sides by 10:-
x = 4

If: y-2+3y =10 Then: y+3y = 10+2 And: 4y = 12 Divide both sides by 4 to find the value of y: y = 3
You will have to break it down, for example: 5x + 40= 60 -40 -40 ----------- 0 20 so 20 divided by 5 is 4 so x equals 4, thats how you do it,.
y=4 x+y=5 so it wud be:::::: x+4=5 solve it from there by doing 1 step equation :)
this is a simple answer. you first do the problem one half of one third, which equals 0.166666667, then you do one fourth of one third, which equals 0.0833333333, then you do one fourth of 690, which equals 172.5 which would be your final answer. You need to take the problem step by step and solve it with a calculate or division to make it easier.
If you meant you want to solve for c on: 5c-3 = 2c+6 you have to simplify the formula. Step 1: Subtract 2c from both sides: 3c-3 = 6 Step 2: Add 3 to both sides 3c = 9 Step 3: Divide both sides by 3 c = 3
