Q. Solve the system by substitution.y=3xy=4x+10(□,□)
Given Equations: We are given two equations y=3x and y=4x+10. We will substitute the expression for y from the first equation into the second equation.
Substitute and Simplify: Substitute y=3x into y=4x+10.3x=4x+10
Solve for x: Solve for x by subtracting 3x from both sides of the equation.3x−3x=4x+10−3x0=x+10
Find y: Subtract 10 from both sides to find the value of x.0−10=x+10−10−10=x
Final Solution: Now that we have the value of x, we can substitute it back into either of the original equations to find y. We'll use y=3x.y=3(−10)
Final Solution: Now that we have the value of x, we can substitute it back into either of the original equations to find y. We'll use y=3x.y=3(−10) Multiply 3 by −10 to get the value of y.y=−30
Final Solution: Now that we have the value of x, we can substitute it back into either of the original equations to find y. We'll use y=3x.y=3(−10)Multiply 3 by −10 to get the value of y.y=−30We have found the values of x and y. The solution to the system of equations is y0 and y=−30.
