y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2
Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3

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
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.
Can the function f(x)52x equal 200?
Sure; a linear function such as this one can be equal to ANY real number.To know at what value of "x" this happens, just solve the equation 52x = 200. (Note: This will not be a whole number.)
What answer is that 3x-11 equals x plus 5?
3x - 11 = x + 5subtract x from both sides:3x - x - 11 = x - x +52x - 11 = 5add 11 to both sides:2x - 11 + 11 = 5+112x = 16divide both sides by 2 to solve for x:2x/2 = 16/2x = 8
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
4x plus 1 equals 52x how do you solve this?
Subtract 4x from each side getting 1 = 48x so x = one forty-eighth
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 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)
What is 27 plus 9 equals -52x plus 40x?
It is an equation and the value of x is -3
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
How do you solve -3x-52x?
you cant solve but you can simplify -55x
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.
Reduce 3x plus 5 2x plus 1?
If you mean solve for X: 3x + 52x + 1 = 0 55x = -1 x = -0.02
What times 52 equals 100?
