This problem can be solved by substituting (x) for the unknown number and (x + 28) as the number that is 28 more than the unknown number. Set up and solve the problem: x + (x + 28) = 156 (then simplify): 2x + 28 = 156 (subtract 28 from both sides of the equation to isolate the known numbers from the unknown): 2x = 128 (divide both sides by 2 to find the value of x) x (the unkown number) = 64 (now use the value of x to prove the answer) 64 + (64 + 28) = 64 + 92 = 156

2X + 8^2 = 2X+64, for whatever value X. If the question is (2x+8)², the answer is 4x²+32x+64 The formula is (a+b)² = a² + 2ab + b². a=2x, b=8, a²=4x², b²=64
find x when, 2x=128 2x=128 /2 /2 x=128 /2 x=64 then check your answer by doing the following if x=64, then what is 2x? 2(64)=? or 2 * 64=? or 2 x 64=? 2 times 64 equals 128!
32. 2x=64 can be written as x = 64/2. 64/2=32
I can help you with that. To find the value of x in the equation 2xβ = 8, we can follow these steps: Cube both sides of the equation: This will get rid of the fractional exponent. (2xβ )Β³ = 8Β³ Simplify the equation: 8xΒ² = 512 Divide both sides by 8: xΒ² = 64 Take the square root of both sides: β(xΒ²) = β(64) Simplify to find x: x = Β±8 Therefore, the solutions for x are 8 and -8.
The answer is 32.
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13

If you mean 2x = 28 then the value of x is 14
If you mean: x-3 = 2x-8 then the value of x works out as 5
