Specifically, we graphed the two equations y = 2x + 5 and y = (-3/2)x + 2, and ... Now, we can set the right hand side of each equation equal to each other because they both equal y. ... x = 5y in the second equation, then x must also equal 5y in the first equation. .... Also, the point (0, 19/14) works, where x = 0 and y = 19/14.

Example 1. Calculate the value of x when y = 0, that is, find the x-intercept of y = 2x + 10. Solution. On putting y = 0, we have to solve the equation,. 2x + 10, = 0. We have: 2x, = −10. x, = −5. ... a) When we have the equation of a straight line, how do we find the ... the same. Find the intercepts by putting x -- then y -- equal to 0.

We need to find two numbers that will mutiply to give us -6. ... If we set one variable to the other we would get y = (2x – 7)/3 or x = (3y + 7)/2, but ... If y = -7/3, then x = 0. ... When you multiply a number by 5 and then subtract 23, the result is the same as ... You set up the equation 5x – 23 = 3x + 3, then solve for x, giving you 13.
