1.4 Problem Set43Solve.61. Find the value of x + y − 4 when62. Find the value of x − y − 3 when_c. x = − ​ 3 5 ​and y = ​8 _5 ​ −3 c. x = −5 and y = −2 −6a. x = −3 and y = −2 −9a. x = −4 and y = 1 −8b. x = −9 and y = 3 −10b. x = 2 and y = −1 0C Rewrite each of the following phrases as an equivalent expression in symbols, and then simplify. [Examples 8–12]63. Subtract 4 from −7.−7 − 4 = −1164. Subtract 5 from −19.−19 − 5 = −2465. Subtract −8 from 12.12 − (−8) = 2066. Subtract −2 from 10.10 − (−2) = 1267. Subtract −7 from −5.−5 − (−7) = 268. Subtract −9 from −3.−3 − (−9) = 669. Subtract 17 from the sum of 4 and −5.[4 + (−5)] − 17 = −1870. Subtract −6 from the sum of 6 and −3.[6 + (−3)] − (−6) = 9C Recall that the word difference indicates subtraction. The difference of a and b is a − b, in that order.
