4x plus 7 plus 3x equals 19 plus xx = 2
if 3x+5=x+19 then x=7
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
3x+4=-11 3x=-15 x=-5
3x + 11 = x + 3 2x = -8 x = -4
X=2
4y = 3x+11 or as y = 3/4x+11/4
7X - 11 = - 19 + 3Xsubtract 3X from both sides4X - 11 = - 19add 11 to both sides4X = - 8divide both sides integers by 4X = - 2=====----------- check in original equation7(- 2) - 11 = - 19 + 3(- 2)- 14 - 11 = - 19 - 6- 25 = - 25==========checks
