5 - 2X = 15
subtract 5 from each side
- 5 + 5 - 2X = 15 - 5
-2X = 10
divide each side by - 2
X = - 5
check
5 - 2(-5) = 15
5 + 10 = 15
15 = 15

How do you solve this -52x plus 3 equals 7?
-52x + 3 = 7 -52x + 3 = 7 -3 -3 -52x = 4 /52 /52 -x = 1/13 /-1 /-1 x = -1/13
What is the solution set of the equation 2x-10 plus 7 equals 5?
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
Why does 2x-3 equals 2x-5 have no solution?
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
What is the value for x in the following systems of equations x-y equals 5 2x plus y equals 7?
x - y = 52x + y = 7 (use the substitution method)y = x - 52x + y = 7 (substitute x - 5 for y into the second equation)2x + y = 72x + x - 5 = 73x = 12x = 4Thus x = 4 satisfies both the equations of the system.
What is true 15 plus 0 equals 0 15-0 equals 0 15 percent 0 equals 0 0 percent 15 equals 0?
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
What is the answer for 52x plus 3 equals 30?
x = 0.52 because: 52x + 3 = 30 52x = 30 - 3 52x = 27 x = 27/52 x = 0.52 ( to two decimal places)
How do you solve this -52x plus 3 equals 7?
-52x + 3 = 7 -52x + 3 = 7 -3 -3 -52x = 4 /52 /52 -x = 1/13 /-1 /-1 x = -1/13
52x - 7 equals 33 - 36x plus 4?
52x - 7 = 33 - 36x + 4 52x + 36x = 33 + 7 + 4 88x = 44 x = 1/2
What is the solution set of the equation 2x-10 plus 7 equals 5?
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
What is the smallest integer value of x Given that -52x less than and equals to 7?
"less than AND equals to" is an impossible condition.
What is 27 plus 9 equals -52x plus 40x?
It is an equation and the value of x is -3
What times 52 equals 100?
Solve algebraically. 52X = 100 X = 100/52 X = 25/13 ---------------- or 1.923076923
Solve 5 2x plus 3equals 30?
Assuming you meant 52x+3=30 52x=30-3 52x=27 x=27/52 or approximately 0.51923
What is the answer for 2x-5 equals 3?
Adding 5 on both sides, we get2x-5+5 = 3+52x = 8Dividing both sides by 2x = 4
4x plus 1 equals 52x how do you solve this?
Subtract 4x from each side getting 1 = 48x so x = one forty-eighth
Why does 2x-3 equals 2x-5 have no solution?
2x - 3 = 2x - 52x = 2x - 22x - 2x = -20 =/= -2Zero is not equal to -2 so the answer is no solution.
