4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5

5y = 4x - 35 Divide each side of the equation by 5 : y = 4/5 x - 7
x=36From superscot85: It does not!2x + 7 = 79Subtract 7 from each side: 2x = 72Divide each side by 2: x = 36
The question contains an expression but not an equation nor inequality. There is therefore, nothing that can be solved.
3p = 2p + 12 subtract 2p from both sides 3p - 2p = 2p - 2p + 12 1p = 12 p = 12 this is how you solve this problem.
The subtraction of equality.

The equation 10b = 11 can be solved for b by dividing both sides of the equation by 10. b = 11/10 or 1.1
You cannot.!!!! Because it is an Algebraic Expression NOT an Algebraic Equation; there is NO 'EQUALS (=)' sign.
If: 14x = 56Then x = 56/14Therefore: x = 4
you use a calecutor with graph on it!
Not sure that you can slove anything. -2w = r + s is one linear equation in 3 unknown variables. You need three independent equations in 3 variables to be able to solve them.
5y = 4x - 35 Divide each side of the equation by 5 : y = 4/5 x - 7
This expression can be simplified to: 2-6x
y = 5
murder the person...operation done
