Math Problem Statement
Solve the system of equations.
[\begin{aligned} & -4x+3y = -2 \\ & y=x-1 \end{aligned}]
Solution
To solve the given system of equations:
& -4x + 3y = -2 \tag{1} \\ & y = x - 1 \tag{2} \end{aligned}$$ ### Step 1: Substitute $$y = x - 1$$ (from Equation (2)) into Equation (1) Substitute $$y$$ into the first equation: $$-4x + 3(x - 1) = -2$$ Simplify: $$-4x + 3x - 3 = -2$$ Combine like terms: $$- x - 3 = -2$$ Add 3 to both sides: $$- x = 1$$ Solve for $$x$$: $$x = -1$$ ### Step 2: Substitute $$x = -1$$ into Equation (2) Now substitute $$x = -1$$ into $$y = x - 1$$: $$y = -1 - 1$$ $$y = -2$$ ### Final Solution: The solution to the system of equations is: $$\boxed{x = -1, y = -2}$$ ### Verification: 1. Substitute $$x = -1$$ and $$y = -2$$ into Equation (1): $$-4(-1) + 3(-2) = 4 - 6 = -2 \quad \text{(True)}.$$ 2. Substitute $$x = -1$$ into Equation (2): $$y = -1 - 1 = -2 \quad \text{(True)}.$$ The solution satisfies both equations. --- Do you want further explanation or have questions?
