When we solve the system of equation, y = 4x - 7 and y = 2x - 1 using substitution, the result obtained are:
How to solve the equation using substitution method?
The system of equation y = 4x - 7 and y = 2x - 1 can be solved using substitution method as illustrated below:
y = 4x - 7 ........ (1)
y = 2x - 1 ......... (2)
Substitute the value of y in equation (2) into equation (1) to obtain the value of x. Details below:
4x - 7 = 2x - 1
Collect like terms
4x - 2x = -1 + 7
2x = 6
Divide both sides by 2
x = 6 / 2
x = 3
Now, substitute the value of into equation (2) to obtain the value of y. Detials below:
y = 2x - 1
y = 2(3) - 1
y = 6 - 1
y = 5
Thus, the solution to the equation are:
