How do you add 2x plus 3y equals 18 in 5x-y equals 11
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
0. 6x + 3 = 5x + 141. 6x = 5x + 11 [subtracting 3]2. x = 11 [subtracting 5x]
yes there is.-5x+1=-10-5x=-11-x=-11/5x=11/5
(10,13)
4
5x + 51 = 9x + 11 Becomes 40 = 4x So x = 10
x= -11
33
swop sides: 10 = 5x - 1 ie 11 = 5x so x = 2.2
