'Five ecks(x) plus two'.
or
'Five ecks add two.
or
Five multiplied to ecks(x) plus 2.
a= 5x+-7
This would usually be written as:5n 5x 5a etc., i.e., 5, immediately followed by the desired variable.
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
let x represent the number 2x+8= 5x 2x-5x= -8 -3x= -8 -3 -3 x= 2.67
5x-5x = 0

-12x-2Given: -5x-(7x+2)This is the same as -5x-1(7x+2). Use the distributive property and multiply the -1 through (7x+2).-5x-7x-2Simplify.-12x-2
2x2-2 = -5x-1 2x2+5x-2+1 = 0 2x2+5x-1 = 0 Use the quadratic equation formula to find the values of x: x = 0.1861406616 or x = -2.686140662
Let x represent the number. 2 times the number would be 2x, and 5 times the number would be 5x. The sum of the two would be 2X + 5x = 7x
