3+3x+7x=13 3x+7x=10 10x=10 x=1
7x+3=10x-9(shift +3 & 10x) 7x-10x=-9-3(signs changed) -3x=-12(divide both sides by -3) x=4
10x + 5 which is also equal to 5(2x + 1)
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
8y-7x
-15-3x=6-10x -15=6-7x -21=7x x=3
7x2-10x+3=0 (7x-3)(x-1)=0
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
10x+15 = 7x-21 10x-7x = -21-15 3x = -36 x = -12 Which is the solution to the above equation when simplified.
3+3x+7x=13 3x+7x=10 10x=10 x=1
There is no symbol between 7x and 31. Please resubmit using words eg "plus", "equals" etc.
7x+3=10x-9(shift +3 & 10x) 7x-10x=-9-3(signs changed) -3x=-12(divide both sides by -3) x=4
7x = 3 x = 3/7
y=-10x-4
10x + 5 which is also equal to 5(2x + 1)
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
7x-4020+3x= 7x+-4020+3x= 7x+3x+-4020= 10x+-4020= 10x-4020
