How do you slove 3x plus 1 plus 4x-5 equals 31?
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
4xy plus 1 equals 3y-7x solve for y?
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
What is the answer to 4x plus y equals 9 and 7x-8y equals 6?
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
7x-9 equals -10 plus 4x?
x = -1/3
4x plus y equals 9 7x - 8y equals 6?

How do you slove 3x plus 1 plus 4x-5 equals 31?
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
4xy plus 1 equals 3y-7x solve for y?
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
What is the answer to 4x plus y equals 9 and 7x-8y equals 6?
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
Can you solve neg 4x minus1 minus 3x minus4 plus 5 equals neg 7x minus 1 minus 2x plus 1 plus 6?
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
What is 4x plus 6 minus7x plus 9 equals 18?
4x+6-7x+9=18-3x+15=18-3x=3x=-1
How do you Factorise this 12x square 7x plus 1?
12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
3x-7 plus 4x equals 28?
3x - 7 + 4x = 28 7x - 7 = 28 I added 4x and 3x to get 7x 7x = 35 I subtracted 7 from both sides x = 5 I divided by 7 on both sides
How do you Factorise this 12xsquare-7x plus 1?
12x2 - 7x + 1 = 12x2 - 4x - 3x + 1 = 4x(3x - 1) - 1(3x - 1) = (3x - 1)(4x - 1)
How do you solve 3x equals 7-4x?
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
How do you solve this eqation 7x plus 2 equals 3x-2 what is the value of x?
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
