There is no equation in the question, only an expression.
It is an equation because it is telling us that one thing is equal to another. We solve for the value of a like this:2a + 45 = 5aIf we subtract 2a from both sides of the equation (from both sides in order to keep things equal) we get:45 = 5a - 2aWe can now simplify the right side of the equation by calculating 5a - 2a to get:45 = 3aIt reads better to write this as 3a = 45.Now if we divide both sides of the equation by 3 we will end up with "a" on one side:a = 45/3a = 15.
e+4-9=45 (write down the equation) e-5=45 (simplify 4-9) e=50 (add 5 to both sides) Answer: e=50.
The equation for the line can be written in slope-intercept form as y = mx + b, where m is the slope and b is the y-intercept. Since we know that the slope is -45 and the point (1, -5) lies on the line, we can write the equation as y = -45x + b. To find b, substitute the x and y values of the point into the equation and solve for b: -5 = -45(1) + b. Simplifying the equation gives b = 40. Therefore, the equation for the line is y = -45x + 40.
