I tried to help hope this helps
Step 1: Add the two equations.
Step 2: Solve for x.
Step 3: To find the y-value, substitute in 3 for x in one of the equations.
Step 4: Solve for y.
Step 5: Identify the solution as an ordered pair.
What if adding or subtracting does not eliminate a variable? Example. 3x – y = 8. x + 2y = 5.
MARK AS BRAINIEST PLEASE
Calculate the products
5x+6x-21x+2
Combine like terms
-10x+2
• rearrange into the form y = mx + c to find the gradient:
5x -3y = 2
-3y = 2 -5x
y = (-5/-3x) + (2/-3)
y = 5/3x - 2/3
gradient of line m is 5/3
• use formula to find perpendicular gradient, m1 X m2 = -1, and rearrange:
5/3 X m2 = -1
m2 = -3/5 is the slope of the perpendicular line :)
