Solve linear equation by substitution
WebGood evening. One way would be to substitute the y in Your first equation with the entire right-hand side of Your second equation (which, as You can see, is equal to y): `y = -2x + … WebOct 10, 2024 · Take that value of x, and substitute it into the first equation given above (x + y = 3). With that substitution the first equation becomes (1+y) + y = 3. That means 1 + 2y = 3. Subtract 1 from each side: 2y = 2. So y = 1. Substitute that value of y into either of the two original equations, and you'll get x = 2.
