Solving systems of three linear equations - Krista King Math
WebNow we want to solve for our y value. And we could substitute this back into either of these two equations. Let's use the top one. You could do it with the bottom one as well. So we know that 3 times x, 3 times 7 over 2-- I'm just substituting the x value we figured out into this top equation-- 3 times 7 over 2, plus 4y is equal to 2.5. WebSolution. We can obtain an equation in one variable by adding Equations (1) and (2) Solving the resulting equation for x yields. 2x = 6, x = 3. We can now substitute 3 for x in either Equation (1) or Equation (2) to obtain the … WebJan 6, 2024 · Exercise 5.3.12. Solve the system by elimination. {7x + 8y = 4 3x − 5y = 27. Answer. When the system of equations contains fractions, we will first clear the fractions by multiplying each equation by its LCD. Exercise 5.3.13. Solve the system by elimination. {x + 1 2y = 6 3 2x + 2 3y = 17 2. nothing on but the radio gary allan
