Use the function image to find the solution of the following equation, and check by written calculation. (1) 5x-1 = 2x + 5 (2) 1 / 2X-4 = 3x + 2 use the function to sit and wait for the answer (no drawing,
Building owner,
(1) , item transfer: 3x = 6
Divide both sides by 3 to get x = 2
Test: substitute x = 2 into the original equation: left = 5 × 2-1 = 9, right = 2 × 2 + 5 = 9, left = right
(2) item transfer: 2.5x = - 6
Divide both sides by 2.5 to get: x = - 2.4
Test: substitute x = - 2.4 into the original equation: left = 0.5 × - 2.4-4 = - 5.2, right = 3 * - 2.4 + 2 = 5.2, left = right
The above is my answer process, I hope to help you!
By hand,
