5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
It is a linear equation in the variable x. You can solve for x using algebra: -5x + 3 = -22 -5x = -25 -x = -5 x = 5
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
2x + 5x = 35 7x = 35 x = 35/7 x = 5
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
x=6
If its x+4x+5 then: 5x+5
x+4x+5=5x+5
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
x = 27
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
you would first do 10+5x-5=0, then 5x+5=0 and is factored by 5(x+1)=0. or if you want to know what x equals with, x=-1
yes there is.-5x+1=-10-5x=-11-x=-11/5x=11/5
5
x = -5
