The easiest way to solve this system of equations is to solve for a variable in one of the equations. In the second equation, y = 3x. This can be substituted into the first equation:
y = -4x - 7;
3x = = -4x - 7;
7x = -7;
x = -1.
Since we have determined that x equals -1, we can then substitute -1 into either equation to find our corresponding y-value. Thus:
y = 3x;
y = 3(-1)
y = -3.
Thus, the solution to this system of equations is (-1, -3).

Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
How do you solve this. in parallelogram abcd diagonals ac and bd intersect at e if ac 4x plus 6 and ae equals 3x minus 1 find the value of x?
this is what you would: 4x+6=3x-1 -6 -6 ---- 4x=3x-7 -3x -3x ---- 1x=-7 ---- x=-7
4x equals 3x plus 1 what is x?
4x=3x+1 => (4x-3x)=1 => x=1 therefore the value of x is 1.
3x plus 4x equals 84 7x equals 84?
3x + 4x = 847x = 84divide both sides by 7x = 12
Use the substitution method to solve the system of equations Enter your answer as an ordered pair 3x plus y equals 10 y equals x - 2?
3x+y = 10 y = x-2 Substitute the value of y into the top equation: 3x+x-2 = 10 => 4x = 10+2 => 4x = 12 => x = 3 Substitute the value of x into the original equations to find the value of y: So: x = 3 and y = 1
