The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Isolate for "x" x = 3 - y ----- eqn 3. Thus, The correct system of equations which can be used to determine x, the number of 1-inch-thick books in the stack, and y, the number of 2-inch-thick books will be; ⇒ x + y = 9. Multiplying 2nd equation by two and adding both equation. For x = 0 (10 * 0) + 2y = 14 0 + 2y = 14 2y = 14 (2y)/color (red) (2) = 14/color (red) (2) y = 7 or (0, 7) For x. The solve by substitution calculator allows to find the solution to a system of two or three equations in both a point form and an equation form of the answer. 12y−(2y+14) = 8(2y +5) 12 y - ( 2 y + 14) = 8 ( 2 y + 5) Simplify 12y−(2y+14) 12 y - ( 2 y + 14). what are the coordinates for the center of the circle and the length of the radius? verified. What are the coordinates for the center of the circle and the length of the radius? Answer by reviewermath(1029) (Show Source):. 6x+2y=14,-x-4y=6 To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Tap for more steps y = − 7 2x+7 y = - 7 2 x + 7.
