-52x + 3 = 7 -52x + 3 = 7 -3 -3 -52x = 4 /52 /52 -x = 1/13 /-1 /-1 x = -1/13
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.)
How do you solve 4y plus x equals 8
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.
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
